Milwaukee Heated Workskin Base Layer

Milwaukee Heated Workskin Shirt Keeps You Warm on the Job

The Milwaukee Heated Workskin Base Layer shirt, powered by a RedLithium USB, uses carbon fiber heating elements to create and distribute heat across your chest and back. Where battery-powered heated jackets usually use a clunky 12V battery for power, this base layer uses a slim battery only slightly larger than your standard AA battery. Depending on how cold it is on the jobsite, this base layer can be worn as a solo jacket or as a piece of a more comprehensive heating solution.

Milwaukee Heated Workskin Shirt Features

Apart from the smaller battery pack—which really is a headline all in itself—the Milwaukee Heated Workskin Base Layer represents the company’s first heated “shirt”. Having previously reviewed the Milwaukee Workskin base layer, we love the existing design. Adding heating elements to the front and back just makes it more versatile. This Milwaukee heated shirt has a lot of features designed to keep you at your warmest and most productive—particularly when worn underneath additional gear.

Milwaukee designed the heated Workskin Midweight Base Layer with carbon fiber heating elements across the chest and back. A one-touch LED controller lets you choose between two heat settings. Finally, the Milwaukee Quick-Heat function heats up the shirt over 3x faster than prior technology.

The Milwaukee Workskin combines a double-lined polyester body with fleece-lined arms. The raglan-style sleeves and seamless shoulders won’t restrict your arm movement, making for a comfortable top.

The Milwaukee WorkSkin Heated Base Layer runs for up to 3 hours on a charge. The fabric resists pilling and is safe to run through the washer and dryer.



The Milwaukee Workskin Heated Base Layer kit comes with the shirt, a RedLithium USB 3.0Ah battery, a USB battery controller/charger, and a 3 ft. micro-USB cable and 2.1A wall charger. It comes in S, M, L, XL, 2X, and 3X sizes. All of this retails for $149.
